Tens of millions of Internet users will be cut off from encrypted webpages in the coming months unless sites are permitted to continue using SHA1, a cryptographic hashing function that’s being retired ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

From mismanaged encryptions keys and system errors to eventual crypto cracking, Public Key Infrastructure (PKI) encryption has increasingly become more difficult to maintain as the needs for these ...
